These are acoustically-transparent filters within the inside of the tips that block ear wax and debris (WaxGuard™) or sweat and moisture (SweatGuard™) from entering the soundport nozzle of your earphone. These filters help protect your earphones over time from blockage, compromising the sound quality. It is highly recommended for high-end earphones and sport earphones.
